Growing Double Rich Tomatoes in the Vegetable Garden

To cultivate Double Rich Tomatoes, start by sowing seeds indoors 6-8 weeks before the last frost date. Plant seeds 0.25 inch deep in a well-draining mix of vermiculite, finely sifted compost, and washed river sand. Maintain a consistently warm environment, ensuring temperatures stay above 65 F for optimal germination. As the seedlings develop two true leaves, transplant them into individual containers. Once all risks of frost have passed, typically 60-80 days from transplant, move the robust seedlings to their permanent outdoor location.

Throughout the growing process, prioritize proper maintenance for a successful harvest. Double Rich Tomatoes benefit from consistent moisture, particularly during dry spells, to prevent issues like blossom end rot. Provide support for the prolific vines by using stakes or cages. Companion planting with basil, parsley, and chives can help deter pests and enhance growth. Regularly prune the lower foliage to improve air circulation and minimize disease risks.

Harvesting Double Rich Tomatoes

Identifying the ideal harvest time for Double Rich Tomatoes is crucial for flavor and quality. This indeterminate variety typically matures in 60-80 days. Harvest when the tomatoes are firm, fully colored, and reach a size of 7-8 cm. The high crack resistance and extended shelf life make it easier to gauge ripeness. Simply twist or cut the tomatoes from the vine, ensuring minimal damage. As an indeterminate variety, Double Rich will continue producing throughout the season, providing a steady supply for canning and juicing.

About Double Rich Tomato Garden Seeds

Developed in 1953 by A. Yeager at the University of North Dakota and the University of New Hampshire, Double Rich Tomato, also known as Doublerich, has a storied history. This productive heirloom gained popularity for its firm, mild-tasting 7-8 cm globes, and its impressive nutritional profile, boasting high amounts of vitamin C—said to surpass that of an orange.

While not explicitly bred for a specific trait, Double Rich Tomato has unique characteristics that set it apart. It is known for its rich, delicious flavor, firm texture, and high vitamin C content. Its adaptability makes it suitable for various growing climates, and it thrives in well-draining soils with adequate moisture.

Double Rich stands out for more than just its nutritional content. This heirloom variety exhibits remarkable crack resistance and boasts an extended shelf life, making it a reliable choice for home gardeners and market growers alike. Its deep red flesh and exceptional taste make it a favorite for fresh eating, canning, and juicing.

While Double Rich Tomato is typically grown in traditional garden plots or raised beds, it can also be adapted for container gardens. Choose large containers to accommodate the indeterminate growth habit, and provide sturdy support. Hanging baskets are not recommended due to the weight of the tomatoes and the need for substantial support for the vines.
